Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16912, here are decompositions:
- 11 + 16901 = 16912
- 23 + 16889 = 16912
- 29 + 16883 = 16912
- 41 + 16871 = 16912
- 83 + 16829 = 16912
- 89 + 16823 = 16912
- 101 + 16811 = 16912
- 149 + 16763 = 16912
Showing the first eight; more decompositions exist.
